Descripción

General description

Bromoform is a major organic source for atmospheric reactive bromine BrO_x(Br+BrO). It is formed as a product of chlorination of drinking water. It undergoes photodissociation to form the Br₂ fragment and mechanism has been investigated by cavity ring-down absorption spectroscopy.

Application

Bromoform was used to evaluate the genotoxicity of chlorodibromomethane, bromodichloromethane and bromoform.

Molecular elimination of Br2 in 248 nm photolysis of bromoform probed by using cavity ring-down absorption spectroscopy.

Hong-Yi Huang et al.

The Journal of chemical physics, 121(11), 5253-5260 (2004-09-09)

By using cavity ring-down spectroscopy technique, we have observed the channel leading to Br(2) molecular elimination following photodissociation of bromoform at 248 nm. A tunable laser beam, which is crossed perpendicular to the photolysis laser beam in a ring-down cell

Assessment of the potential in vivo genotoxicity of three trihalomethanes: chlorodibromomethane, bromodichloromethane and bromoform.

K J Stocker et al.

Mutagenesis, 12(3), 169-173 (1997-05-01)

Chlorination of drinking water results in the formation of chlorodibromomethane, bromodichloromethane and bromoform. These trihalomethanes have all shown evidence of genotoxicity in bacterial and mammalian cell systems in vitro and some evidence of carcinogenicity in rodents. Chlorodibromomethane and bromodichloromethane have
